  "title": "Improper signature verification in OpenCart Virtual POS Module",
  "summary": "OpenCart Virtual POS Module versions 26.8.2 through versions before 26.9.1 improperly verify cryptographic signatures. An attacker may spoof signatures where the vulnerable signature-validation path is reachable; the evidence does not identify additional preconditions.",
